PORT ELIZABETH, South Africa --

Paris Hilton's companion, who was convicted of possessing marijuana, was ordered to leave South Africa.A spokesman for the immigration department said Saturday that Jennifer Rovero had two weeks to leave the country and would not be welcome back for at least two years.

Hilton was arrested along with Rovero after Friday's Brazil-Netherlands match in Port Elizabeth on suspicion of possession of marijuana. Hilton's case was dropped at a midnight court hearing.

Rovero, a former Playboy playmate of the month, "acknowledged to be in possession of cannabis, and pleaded guilty," said a spokeswoman for South African police.

Rovero, a 31-year-old New Yorker, was sentenced to a fine of 1,000 rand ($130) or 30 days imprisonment, De Beer said.

Hilton wrote on Twitter later: "Hey guys, there's a lot of crazy rumors going around. Just want you all to know the truth. Everything is completely fine. I was not charged or arrested, cause I didn't do anything."

This isn't the heiress' first run-in with the law. In 2007, Hilton pleaded no contest to alcohol-related reckless driving and was sentenced to 45 days in jail.
